The original Iron Man comiquettes come with a COA (certificate of authenticity) from sideshow, but it's casted within the IM statue's core, so the only way you know you have a real one is if you break it open.
After realizing their mistake, on future Marvel grails, SS will now embed a chip that transmits a signal to verify the authenticity of the statue. You'll need an antenna, demodulator, and key decrypter to verify the received signal. Bummer, and good luck in your search.
